In addition the advice from csorhand and looking at your processes it appears that you are using a LAMP configuration, so there are several things to take into account here (I am assuming the php part).
1. Examine your content, if you are serving pages that contain mixed content such as images and javascript along with dynamic php content, you might benefit from adding expiry to the static content, if client need to download less that will reduce some of your load.
2. Install a php cache such as xcache, eAccelerator or APC.
3. Look at this thread https://www.unix.com/web-programming-...primer-sh.html and use the tools linked to check your mysql configuration. I believe it is actually your communication with MySQL which is causing you the most problems.
4. Ensure that you have dns lookups turned off in apache:
Also check for "bad" pages that have nasty queries. We has on module on this site that put millions of rows in one db table, and tried to query that table every time specific pages were loaded. The server was running flat out for a few days until I managed to spot the strange behavior and truncated the table. The load went down instantly to a normal level.
CPU usage: PS versus TOP - Different output
Hi
When monitoring a Linux environment with PS command, reported CPU value for a certain process differs, sometimes greatly, from the value seen in TOP.

I am running a Dell PE R815 with 4 x AMD 12 core CPUs with 128GB of RAM and a RAID 5 array of 6 SAS disks. This is an HPC application and is definitely CPU bound, however once I run 16 of these processes (thus pinning 16 cores) the work performed slows down dramatically, to maybe 5 or 10% of what...

gftp
GFTP(1) General Commands Manual GFTP(1)NAME
gftp - a graphical ftp client
SYNOPSIS
gftp [options] [[proto://][ user : [pass] @] site [: port ][/ directory ]]
DESCRIPTION
gFTP is a multiprotocol file transfer program for X Windows and the console. It features support for the FTP, SSH, HTTP, and local file
system protocols, simultaneous downloads, resuming of interrupted file transfers, file transfer queues, downloading of entire directores,
ftp and http proxy support, remote directory caching, bookmarks menu, stop button and many more features
OPTIONS
You may enter a url on the command line that gFTP will automatically connect to when it starts up.
--help, -h
Display program usage, and quit
--version, -v
This will display the current version of gFTP, and exit
--download, -d
This tells gFTP to download the files and directories specified in the url passed on the command line.
user This is the username that you will login as to the remote site. If no username is supplied, the default is to login as anonymous.
pass This is the password you will use to login to the remotesite. If you do not enter a password, then gFTP will ask you for one when it
starts up. I do not recommend entering your password on the command prompt. Anyone that has access to your machine will be able to
see your username and password with the ps(1) command. If you are logging in as anonymous, you do not need to pass a password since
gFTP will automatically send your email address as your password.
site This is the remote site you want to connect to
port This is the port that the remote server is listening on. If you do not enter a port, it will default to using the ftp port listed in
the services(5) file. If the entry doesn't exist there, it will default to port 21.
directory
This is the default directory to change to once you are connected to the remote server.
FILES
~/.gftp/gftprc
Per user configuration file. This file is commented very well, so that is why there isn't a manpage for it. Most of the options in
here can be set inside gFTP itself.
BUGS
If you find any bugs in gFTP, please report them directly to the author.
